I have just run into this myself. I believe Helmut was referring to "UnSubscribe / Subscribe" when he mentions "export / import". Perhaps that minor translation issue is part of the cause of lack of responses. The error messages show in the Subscribe column, and I believe there is one entry for each folder I have on the server. (lots) I am running Cyrus IMAPd with the unixhierseperator. The folder delimiter is "/". I am already subscribed to all of the folders. -------- Warning: preg_match() [function.preg-match]: Unknown modifier '/' in /usr/local/www/squirrelmail/functions/imap_mailbox.php on line 758 ... (repeats hundreds of time) ... No folders were found to subscribe to! -------- /usr/local/www/squirrelmail/functions/imap_mailbox.php: ------- 758: if((preg_match('/^inbox'.quotemeta($delimiter).'/i', $mailbox)) || 759: (preg_match('/^'.$folder_prefix.'/', $mailbox)) || 760: ( isset($boxesallbyname[$parentfolder]) && (strlen($parentfolder) > 0) ) ) { ------- I suspect Helmut may have $folder_prefix specified as something like "INBOX/" to get the error on line 759 as well as 758. http://php.net/manual/en/function.quotemeta.php: ------- string quotemeta ( string $str ) Returns a version of str with a backslash character (\) before every character that is among these: . \ + * ? [ ^ ] ( $ ) ------- That doesn't list "/" so I am wondering if that is the problem. I wonder if it would be possible to choose a different regex delimiter(?) rather than "/". Something like "#", or something else which is not allowed as part of an IMAP mailbox name per the specs and reality. I haven't checked to see what characters that would leave available. I also don't have an install of squirrel mail which is not in production so I am afraid to test this suggestion without input from those who know more about the topic than I. In other words: 758: if((preg_match('#^inbox'.quotemeta($delimiter).'#i', $mailbox)) || 759: (preg_match('#^'.$folder_prefix.'#', $mailbox)) || 760: ( isset($boxesallbyname[$parentfolder]) && (strlen($parentfolder) > 0) ) ) { Thank you for your assistance.
